15000 ohms. Typically, the 25°mark on a liquid level dial is set to the center of the potentiometer range, and the high and low readings are simply ratios of the angular deflections from the “normal”(QualiTROL gauges use a 340 angular degree potentiometer on a 2:1 gear ratio from the dial travel to the potentiometer travel). -

Viewing Mode Scrolling Viewing Channels ( Power up,<enter> The QualiTROL Electronic Transformer Monitor upon power being applied automatically begins to monitor the inputs and controls outputs based on the factory configuration specified by the customer. The display however, shows only time/date. It will remain in this state until the ENTER key is depressed, at which time the display will go into Viewing Mode scrolling and will Auto Scroll all of the parameters being monitored at a frequency of two seconds. - Page 23 ETM automatically reverts to Auto Scroll, or pressing the Menu button again reverts back to Viewing Mode scrolling. Qualitrol recommends resetting the maximum values immediately after setting up the unit to avoid any erroneous readings caused by the installation.
